Document Summary

Sensation & perception: senses only as reliable as of 2 things: what is in real world, capacity of sensory system. Light waves & wavelengths (colour processed in brain not eyes) Light sensitivity & intensity: rods more sensitive to light (nighttime vison, colour depends on context and contrast. Senses: sound (ear, hearing, theories of pitch perception, touch (heat/cold, pain - gate control theory, taste & smell (flavour-90% smell, subliminal perception - "below threshold" Perception: construct our world, visual perception, distance & depth, size, shape, form, nurture/nature and development, we think constructing our world involves an innate ability but all perceive different, assumptions. Innate ability: accuracy, shared experience, examples of errors in construction (clothing colour in daylight/dim light, objects, selective attention not as careful as should be (eg. gorilla) Visual perception: visual species - cortex area devoted to visual experience, active process vs. passive experience, retinal image 2-d. Distance and depth: binocular, retinal display (2 eyes slightly different images)
